Pocket filters
Pocket Air Filters
Overview
Pocket air filters are essential components of ventilation and air conditioning systems. They can serve as:
- Primary filters for final air purification
- Pre-filters in complex ventilation systems
The main purpose of these filters is to efficiently clean incoming air and filter the exhaust air removed from industrial and other facilities.
Pocket filters are suitable for various environments, especially where high air quality and cleanliness are required.
Filtration Classes
Filters are classified based on the type of filtering material used:
- G3-G4 – Coarse filtration: Captures large dust particles, lint, and abrasive particles.
- M5-M6 – Medium & fine filtration: Traps smoke particles and pollen.
- F7-F9 – Ultrafine filtration: Captures smoke particles and bacterial flora.
Harmony-Technofilter manufactures a full range of pocket filters in accordance with these filtration classes.
